The Drug Enforcement Administration said this week it will reverse its decision to temporarily make kratom a Schedule I drug, NPR reports. The reversal comes in the wake of protests by advocates, scientists and kratom vendors.

The Drug Enforcement Administration’s decision earlier this month to make kratom a Schedule I drug is facing resistance from advocates who say they use the drug to cope with a variety of medical issues including post-traumatic stress disorder, alcoholism and fibromyalgia.

Alabama recently became the sixth state to ban the herbal supplement kratom over concerns about its potential for addiction. Wisconsin, Vermont, Tennessee, Indiana and Arkansas have also banned the supplement.

The drug kratom is being used by some people as an alternative to heroin and other illegal drugs even though it, too, can be addictive, The New York Times reports. Kratom is increasingly popular and easily available.
